Regularise offload feature settings

This is partly preparation for use of the new net device features API,
but is useful in its own right.

Replace repetitive code for getting/setting offload flags with data-
driven loops.

This changes error messages to use the same long names for offload
flags as in dump_offload(), and changes various exit codes to 1.
